Summer 1997

Input/Output

Bullet In -May 7,1997
By all accounts of those present, the
1997 North American QL Show was a suc-
cess! Probably the best one yet.

It was good to see some old friends
again and it was also good to see some new
faces and to be able to put those faces to
names. The location was good with easy ac-
cess to the hotel and show site and plenty of
good restaurants nearby including the one
that the show was held at.

The Aurora card for the QL seems to
have been a big hit as it sold without even
having a demo! The system intended for the
demo impressed someone enough to offer
Frank Davis of FWD Computing an offer he
couldn't refuse! From what I heard and saw,
Aurora sold quite well anyway.

European dealers present were: Stuart
Honeyball of Miracle Systems, Roy Wood of
QBranch, and Jochen Merz Software. There
were a few other European visitors who
came just for the show. Stuart was there to
support Miracle's products now being sold
by Qbranch. Roy had a number of programs
available including ProWESS and the new
version of LineDesign. Jochen was busy
with updates including impressive new ver-
sions of QD and QMenu along with sales
and renewals of QL Today.

American dealers present were: Frank
and Carol Davis of FWD Computing, Paul
Holmgren, NESQLUG, and QBox-USA (we
had a small number of Quanta items for
sale). FWD had Aurora cards for sale along
with a wide range of software for the QL.
They also had lots of Z88 items. Paul had
lots of older and used goodies for sale and
seemed to have quite a popular table.
NESQLUG was selling memberships and
renewals along with Wood and Wind Com-
puting's products.

The latest issue of QL Today debuted at

the show and a quick look reveals that this
magazine just keeps getting better. There is
also news of a number of new items planned
or in progress for the QL.

All in all, the 1 997 show was great, there
was lots of enthusiasm and optimism and ifs
quite possible that there will be a show at the
same site in 1 998. Stay in touch!

AC Adapter for the Z88

I had several 1 10 volt AC to 6 volt DC mains adapters
so I checked them out Two had just less then 6 volts DC
while marked 6 VDC and one had an even 16 VDC. The
latter was a TS-2020 mains adapter. The plug fitted, polar-
ity was correct and the amperage (current) was high
enough so I tried it Be forewarned, the voltage is" too high
since the screen did a runny thing and the Z88 ended up
with a locked-up keyboard. A 7.2 volt battery pack is rec-
ommended so that 7.2 volts DC must be near the top limit
of allowable voltage. The computer seems to be OK after a
soft reset. 0/0

Donald S. Lambert
The power supply must not not exceed 7.2 VDC.

Well, Abed, I'm going to SEND this to you line by line !!!

Regarding Gil Parrish's excellent article on LKDOS,
let me mention another "basic disk handling function," by
citing the FORMAT key, below the key for "8" .
FORMAT is handy, since it formats a disk, as follows :
Track/Side 000/002
Track/Side 003/002
Track/Side 006/002
Track/Side 009/002
Track/Side 012/002
Track/Side 015/002
Track/Side 018/002
Track/Side 021/002
Track/Side 024/002
according as the number n of banks be 0, 1, 2, 3, 4, 5, 6, 7,
or 8, respectively, in the command :
FORMAT "n",
This is very useful, when backing up/restoring
RAMDISK!

We have been using DFM, JFORM, Omn5usT03T~"
Omnibus with pull/down menus, LogiCall, and DUS for
years, due to their ready access to LarKen Disk Utilities.
DFM is by for the most convenient little set of disk file
managers, whereas OMNIBUS and DUShave many unique
routines, amidst their galaxies of capabilities! Coriflning
oneself to LogiCall would be like telecommunicating in
BBS mode ONLY, when a lot of things are better done in

ZXir QJJve Alive!

Summer 1997

TERMINAL mode.

Those of us, who don't mind preceding all disk op-
erations with "RANDOMIZE 100", realize that Larry im-
plemented LKDOS by way of an interrupt at RAM loca-
tion 100 (and 102 for that matter! !) That is very useftil in-
formation, and it gets reinforced with every CALL to disk
operations !

In conclusion, let me state my informed preference
for a screen with black INK (0), white PAPER (7), and
cyan BORDER (5) .

KEEP ON TIMEX'n
. PS. LKDOS might not be such a good choice for new
2068 owners, as there has been no OEM support for years.
But, JLODOS is both compatible with LKDOS and sup-

Dear Abed:

Please tell Don, that Eric Johnson has twenty 2068' s
and Frank Davis has "200"of them. So, there should be
plenty of computers for him to finish his newsletter
project.

In the Want Ads, Doug Wagoner is looking for ter-
minal program(s) to run 2050 modem on TS-1000 and TS-
2068 in cassette format.

Well, RMG Enterprises sells 'em, so I would just give
Rod Gowan a call at 503-655-7484.

y^lJ^^^Q^^3^j9T^3L ( l^L tPJteySL

Right now, I'm looking at a cassette with MTERM I,
on one side for TIMEX models 1000 & 1500, on the other
side for Timex model 2068. Given thirty more minutes,
I'm sure to find MTERM II in the same format, and
MTERM II is better than MTERM II

The Internet address for Jose Moreno is given
as < http://members.tripod.com/~helpme/ >

Weil, somebody better help all us users of the
2068 out here, because we don't have a TILDE (~)
on our keyboard! And, we don't ALL have an
APPOLE, which I am now using to write this letter to
ZQA Magazine. On my local Internet service, we
can all substitute the following three characters in a
row for ~ ...%7E...

Then, Jose's address appears as

Here is a coy of the message, I sent to Gil Parish....

Yes, I have Superdriver : printer utilities by Jack
Dohany. They are distributed by RMG Enterprises. So,
Gil, I would call Rod Gowan at 503-655-7484 to request a
copy.

Dear Abed,

Thanks for this info; but since David has just pointed
me toward Rod Gowan, I apparently don't need David's
address!

Still, your message was helpful in explaining what's
"zXir Qlive Alive!

David's message was. I asked the question some time
back, and I hadn't seen the newsletter yet, so the name
"Superdriver" didn't mean anything to me off-hand today.
Since I work with so many older computers, I wasn't even
thinking Timex/Sinclair until I saw your message. Now I at
least know what he was trying to communicate !

I only just got the AERCO interface fired up a few
days ago; I had some initial panic that it didn't work. Once
I attached the LarKen disk interface, then the AERCO
printer interface, and finally the 2040 printer interface
(since you can have both a large printer and a 2040 on-line
at the same time), I think there was such downward pres-
sure back there that the flex prevented the printer interface
from working. Once I provided some support, it works like
a champ.

Thanks for your help.

Dear Abed,

I got the ZQA! Earlier in the week - Thanks. . . .

I was glad to see the information about the AURORA
QL-replacement motherboard printed in the ZQA! Even if
it is something that I probably won't be getting. I keep
hoping for some information or feedback^om Bill Cable
about the QPC emulator - either directly, or through the
pages of ZQA! and/or NESQLUG News (or any of the
newsletters that Bob has not sent lately).

My disappointment with SMSQ's display would be
increasing with the passage of time if it hadn't occurred to
me to max out the vertical adjustment on the 15" vertical
monochrome VGA monitor that I picked up some time
ago (what was I thinking? . . . ) even so, lot of black space
surrounds the SMSQ display image on all sides. The
monitor has a toggle so the normal DOS display has the
equivalent of about a 12" monitor.

I would guess that using the 15" vertical monitor is
closer to using a normal 20" monitor as far as the height is
about the SMSQ text, when the vertical is maxed out; and,
the resultant height is about the same as DOS text on a 14"
monitor, but the width of the SMSQ generated characters
on the 15" vertical monitor is only about % ths the normal
aspect ratio.

I know that I do not have plans to get a 20" monitor
in order to have a normal sized display; so my mono-
chrome Huge will have to do for now.

I guess too many QDOS/SMSQ users, in general are
too passive (i.e. Grateful for getting anything new) to
complain. Your Pal,

> 1997 North American QL Show

Below is the latest list of people expected at the show.
More people are notifying me every day so it will definitly
be as large a show as we have had in the past few years. *
There is one area that I am a lMs unsure about and I want
to ask for any suggestions or help that any of you might
have. Last year we had a special machine that Al Boehm
was able to borrow for us that projected the computer
display to a large screen. This year that machine will not be
available. I tfiink it is important to be able to display the
demonstrations as well as possbile so I am considering any
suggestions that anyone has. The best alterative that I can
come up with is a device called a PC-TO-TV Video
converter. There are many types and they range in price
from $80 to $300. We may be able to rent a large screen
TV for the show and then with one of these devices we
could have a screen that everyone could see. Has anyone
had any experience with this device? Does anyone have
one they could bring? Could anyopne recommend a brand
or place to buy one? Thanks. I have also promised Jochen
that we would provide a SVGA Monitor for him to use. I
will bring my PC with monitor but it would be good to
have another monitor. Is there anyone who can bring a an

extra SVGA monitor? Thanks for help and suggestions.

Dear Abed,

Tnis is really interesting. We are trying to learn, what
is the best way to send ASCII files over the Internet.
First, we are going to spare you and others the waste of
time, reading our failures, by mailing the e-mail to our-
selves first it

Second, it appears true, that MaxCom has difficulty,
SENDing Word Processor CODES, either MSCRIPT or
AppleWorks in my case !

Third, we have to practice the use of Bill Jones' para-
graph file routine, for sending messages without any punc-
tuation, save perhaps five carriage returns and five line
feeds !! So,

One thing, isolated characters appear to be dropped
by MaxCom, so hopefully you can fill in the "typos" and
missing.

KEEP ON TIMEX'n

Did you consider that the internet is a 7-bit
system and MaxCom is an 8-bit system? Like those
characters dropped by MaxCom.

Also, you cannot send binary files (or pictures)
over the Internet via E-mail. You must first convert
the binary files to ASCII. This process is called en-
coding. You can then send the encoded file over
the Internet using SEND file. The receiver then will
have to decode the file. The most common Internet
file types are MME (MIME text) and UUencoded,
others are XX and BinHex. Of course both the
sender and receiver must have the programs to do
the encoding and decoding. I use a shareware pro-
gram - XferPro - available from the Internet as
XFERP111.ZIP from SabaSoftinc.

http://www.sabasoft.com

Thanks for the info on the Internet and 7-bit systems.
Interesting, but I don't know how we can use that to our
advantage, OR how to avoid any possible disadvantages.
So, can you see any problems, which such formats might
cause upon conflict? Dave

Dear Abed,

Just had my daughter read the Spring '97 ZQA! to me
and I enjoyed it as always.

I noted that there is a mention of a FAX line for RMG
somewhere in the issue. I no longer have the 655-4116
phone line. Jji an effort to lower my cash flow (out), I have

ZXir QLive Alive!

Summer 1997

had to disconnect my second phone line. I will be, as soon
as I can get it done, be putting the fax computer on-line on
my 655-7484 number via a fax switch or a voice/fax/ mo-
dem. It may be a while. I will keep you posted.

I am pleased to note that there are a lot of folks out
there who are still using and enjoying the TS computer
line. I always enjoy the Input/Output column most of all.

I noted that someone (Gil Parrish?) was looking for a
SuperDriver disk for an AERCO printer i/f. He should
contact Jack Dohany, as it is his software. I can no longer
make use of my 2068 as the size, resolution and color of
the screen will not allow me to see what is going on. Oth-
erwise, I could make him a copy of the SuperDriver disk
for LarKen.

I want to let you know that Jose Moreno has put my
price sheets and flyer pages on the Web. I do not know the
address of the page; but I may make some sales from it.

I know you use an IBM clone so I am sending along a
copy of the latest version of RMG UTS utility package.
Take a look at it and see what you think. The
README. 1ST file will tell you what you need to know
about to install and run it. It also tells you what the system
requirements are to run it. If you do not want to try it,
please pass it along to someone who may be using DOS
and who may want an easier way to do things. It is very
comprehensive. You may want to unpack the self-extract-
ing tile UTSPAVEXE and read the UTSMAN.DOC, the
manual for the package. If you ever wanted to learn about
batch programming, this program package could teach you
some tricks.

Let me know what you think, in any case.

Anyone who has purchased a copy of
UTS is eligible for a free update to the
current version if they just send the
original disk and a large SASE with $ 1
postage on it to RMG. The current
version is 3.0d and bears very little re-
semblance to versions before 2.0a. Rod

As I said in November, I am available
to supply TS items and information as I
can as long as folks need it and I can sup-
ply it. I enjoy hearing from TS users any
time. Since my wife died I find it necessary
to keep as busy as possible to keep from
becoming depressed. It can get awfully
lonely after 32 years of having one's help-
mate close and then suddenly being with-
out her.

PS. Abed, you might mention in the next issue of
ZQA! that anyone who has purchased a copy of UTS is
eligible for a free update to the current version if they just
send the original disk and a large SASE with $1 postage on
it to RMG. The current version is 3.0d and bears very Me
resemblance to versions before 2.0a.

Thank you for the disk Rod.

Perhaps you can help me find a user' s manual for the
following software:

MTERM Smart Terminal program version 1.00.
Copyright 1983 by Micro-Systems software, Licensed to
Westridge communications.

This sorrware is on cassette tape, written for the
Timex/Sinclair 2068 computer, controls the Westridge 2050
modem.

I have a vague recollection that an explanatory article
was written by Barry Carter. There may have been an of-
ficial user's manual years ago.

I am using this software to contact the portions of the
Internet through Delphi Online Services.

Would appreciate any helpful information.

You are in luck, I do have both the Westridge
and the Barry Carter manuals. I can make copies
and mail them to you at cost.

If I send you an E-mail message, do I use the address
< akahale@compuserve.com > ? I ask because I thought
Compuserve usernames were composed of numbers only.

Yes, this is my address, Compuserve finally
granted us, users, a name instead of a number. The
number < 103457,2440 > still works though, lam still
a number to them.

Abed,

There will be something Sinclair at the CoCoFest in
Elgin on April 26 after all. At least Don Walterman and
Keith Watson will come down and now John Impellezzari,
it seems, may also get off of work and be able to come.

The purpose seems to be social now more than any-
thing else, Keith says it is a time when he and Don can fi-

and rescheduling it for April 26 at the Holidome, as Holi-

Any of these I can buy used or even new? If I can't
buy them, someone must know where I can get them. I
may also want to get Tasword 3 or even Mscript on car-

4.) Tasword 3, TASWORD 2 for LogiCall is the last one I
ever heard of? I wrote the Driver.

Mscript on cartridge, don't you have a disk drive sys-
tem for the TS2068? a cartridge would get in the way. I can
upload LogiCall to the Club BBS, 847-632-5558. It will be
called LOGICALL.ZIP. You should also download
UTILS.ZIP to use with it. I shall copy this to Abed Kahale
to see if he ever heard of this stuff and maybe put a request
in ZQA! to see if anyone has copies. Bye for now,

Me too, but now more engaged with the PC. I had a
problem with a corrupt disk recently- Nothing in the PC
environment would help to read it and edit the usable parts.
So I hitched up a QL to my multisync monitor and merrily
read sectors into RMA disk then into Chas Dillons
EDITOR.

I really would like to know if anyone has an idea of
how one can get the fecility of Direct Sector Acsess on the
PC, I have QuickBasic , Visual Basics 3&4. but I do no 'C
or Pascal at all.

Just in case you may be interested, I have put a fix for
the PC's year 2000 date failings on the Internet.

I find your Input/Output very informative and good
for a laugh. Jay Shepard

Thank you Jay, I try to diversify with some humor.

Greetings. Just one last message before the show. We
now have 33 people signed up. Roy Wood of QBranch will
also be coming. I have rented a 50" TV and will have a PC
to Video converter for the demonstrations. It should work
with QPC and the MAC emulator and the Aurora card. If
you have a collection of various adaptors and connectors
why not throw them in a tote bag. We are going to be far
from any stores and if we find we need something it would
be good if someone had it with them.

If you know of anyone who hasn't yet decided to
come that might be interested, try one last time to persuade
them. We want the vendors to get as much business as
possible to keep things going.

A few people will arrive on Tliursday evening. Most
will arrive Friday afternoon and evening. If you aren't
corning, wish us well and if you are, see you at the show.

Dear Abed,

Thanks for the disk with printer drivers. You defi-
nitely saved me the effort of looking for the disk with my
Windows drivers on it.

I did receive copies of UPDATE! in the past, but I
didn't remember that Larry Crawford had included the in-
formation that you sent. I also did not realize that he
passed away.

I am sending along the few control codes that I know
which are gleaned from the printer.dat file that came with
the Psion suite for PCs. I used the printer.dat file for the
Epson GQ-3500 and it seemed to work for the KX-P 1 124,
so it is presumably the codes for an

Epson-compatible 24-pin printer.

Translate 1 :

The translate code is one of ten possibles. For example,
you can tell the printer to print one character for another
(i.e., substitute the "@" sign for "€>" sign). I think the
above translate converts to BPS symbol to a "#" (I am pre-
suming CHR$ (35) == #; you can look it up if you are
really curious).

While this information is probably too late for your
day-to-day use, you now have the option of creating a new
printer _driver for your 2068's word processor (Tasword?).
I suppose that there are some other 2068 users who have a
24-pin printer; and so, this information might be generally
useful.

Obviously, I dont know what the control codes are
for changing the fonts via software (vs. the front control
panel). That information (i.e., for changing from Courier to
Script to PS, et cetera) should be in your manual.

Thank you for sending me the Autumn 1996 issue of
ZXir QLive Alive! There seems to be much information in
it about the 2068, Spectrum, and QL, but a paucity of in-
formation on the ZX81 or T/S1000.

Maybe these latter machines are too obsolete techno-
logically speaking. Again, thank you.

Dear Mr. Kahale,

I have a few questions. I have read a few references
to something called "TK82" in T/S puttications including
a "Wanted" ad in ZQA! - Spring '96. What is it?

I have read that the Portuguese Timex Disk System
uses a 17-pin connector to connect the controller to the in-
terface. I have a ZX Microdrive and it uses a 17-pin con-
nector. Are they compatible?

They are compatible with the use of a Twister
Board (Spectrum buss adapter) that was developed
by Nazir Pashtoon

940 BEAU DRAFT 204
DES PLAINES IL 60016-5876

Can anyone give me any information about the
Timex of Portugal products? I want details! At least a
complete list if possible, and a dealer's address if possible.

Thank you,

swer all your questions.

Here is a brief description: The Spectrum com-
patible Portuguese disk drive system was modified
by Zebra Systems Inc. (defunct) for the US market
and sold as Zebra FDD disk drive system, it was
available in one then two disk drives. It has built-in
64K RAM, CP/M, TOS (Timex Operating System),
power supply and controller. It uses Hitachi and/or
Amstrad 3" diskettes.

Dear Don,

Sorry that it's been so long since I have contacted
you. I was somewhat startled awhile back to see a house
listed for sale in the local paper that I thought at first was
yours. Upon checking your house number in the phone
book, I found it was your neighbor across the street.

Among the reasons for my not writing anything
about Sinclair computing for some time are (1) my main
occupation with the jail and prison rriinistry seems to re-
quire more and more time (or I'm just getting slower!), (2)
my eyesight is getting so it is harder to focus on a screen or
printed matter, and (3) after having problems with my main
QL ever since I got it that three different "fixers" failed to
fix; a while back it started crashing almost immediately
upon power-up. In consequence, I began using a PC for

most of my correspondence and record keeping.

That is not to say I was not in Sinclair mode much of
the time, as I have the Psion Four for PC, Tom Wood's
Findex and the Z80 Spectrum/TS-2068 emulator for PC. I
use the Psion Abacus ptogram for all the financial records
and budget reports for contributors to the jail and prison
ministry, and I have setup Findex for addressing
envelopes. Robert Hartung

After sending you the previous letter about my expe-
riences witii my Trump Card QL and running QPC on a
PC, I set up my ZIP drive to use it with QPC also as a re-
movable-disk hard-drive. I also tried it with the Stacker 4.0
compression program and that works fine as well with
QPC fdes on the ZIP drive.

I thought perhaps other QL users who are contem-
plating getting QPC might be interested in some of these
things, so I did the enclosed re-write to clarify the last
paragraph on page two, and also described my use of a ZIP
drive. If you think Abed would want to make an article out
of it, just let me know and I can send him either a hardcopy
as the enclosed, or I can put it on a DOS disk as an ASCII
file if he or you have DOS wordprocessing capabilities.
With best regards,

Yes I can read DOS ASCII disks, whatever is
convenient for you.

Dear Don, ~ """™
... I've been having fun with my TS-1500 with the lull-
sized keyboard. I previously wrote a brief text demo that
runs on a 2K machine, and then I did a more elaborate
version that requires a 1 6K machine. Since the demo takes
a fixed amount of time to run, I got the idea of doing a
multi-part demo for the 2K machine, using the elaborate
version as the basis, with each part automatically loading
and running the next part. And when I say
"automatically", I mean the user doesn't touch the tape
recorder after the initial LOAD; the unit is simply left on
PLAY while all segments LOAD and RUN, one after an-
other. The recorded programs are spread out on the tape
such that when the program is ready to load the next seg-
ments the next segment is right there.

Of course, this has no particular practical application
because recorders run at sHghtly different speeds, and be-
cause (I discovered) running a 2K program on a 16K ma-
chine will have slightly different (slower) timing than on a
2K machine, it would be nearly impossible to develop
tapes for systems other than my own with the proper
spacing (not so wide apart that the wait for the next load is
boring, but not so tightly spaced that a slightly different
setup would run past the start of the second program be-
fore trying to LOAD it. Still it's fun to have a 2K tape-
based machine automatically handle a larger program.
Almost like having Windows use the hard drive as virtual
memory! Well, maybe not almost, but you get the pic-
ture...

Just wanted to thank you for inviting us to the Coco
show. We received a warm welcome from everyone we
talked to. That says a lot for your group since we were not
Coco people.

Would you consider expanding the show for T/S
folks next year? I think if we started talking it up a year in
advance, we might get some more folks there. In fact I'm
going to just mention it this weekend at the QL show and
see how much interest there is. I doubt if the QL show
would merge in but for myself, I'd be happy to go to both
shows. Regards, Don

a few of them. The ones I didn't have were interesting
though. A good set of Syncware news and a pile of the
Boston Computer Society T/S newsletter. Also misc.
newsletters I never even heard of.

We should never need a blank cassette tape again. Let
me know how many dozen you want :-)

After we all go through the stuff, I hope to put a list
together for everyone else to go through.

Sounds like a good idea. I hope it works. I did try
the computer I got at the CoCo fest and it works. Next I
tried it with the twister board and Interfecel and that
worked as well! Next, I going to burn a TX EPROM for

can upgrade the 1 Meg chips to 4 Meg of 1 Meg simms.
The 720k floppy can be upgraded to 1 .4Meg. I can use a
VGA monitor as a 640x400 monochrome monitor if I can
find the unique Atari monitor cable to wire up. Also has an
ASCII port (almost SCSI) that supports hard drives. So,
with some serious work, I can have a 4 Meg Monochrome

strange to run the Atari BASIC. It brings up 3 windows (!)

Looks like Atari support on the web is pretty good.
There is an Atari Tech Usenet group as well. It looks like
I'm going to have to get a regular service like Netcom. I
can't post to Usenet groups from Ford or from the freenet

From: John Impellizzeri To: Don Walterman

Can't wait to see the Atari, really sounds interesting,
especially the 3 windows! Merz does seem to be the ex-
pert on making Atari's into QL's.

I'm frying to do some persuading to get one of the
two days off for the Dayton Hamfest.

Started going thru the stuff from Elgin. Both 2068's
work, the 1000's work but a couple have the dead keyboard
problem. 2040 works. There was a Gladstone 64K RAM
Pack with one of the 1000's that doesn't work along with a
16K that's dead. Couple of others do work. I went thru the
box of books and have another box for you & Keith of
duplicates and copies of books I. have already.

With sadness, our President and friend Harvey Rait, passed
away in the middle of April. Harvey's daughter called me

and stated that the service would be held on Sunday
morning, April 28th, Rockville Centre, NY. Bob Malloy
posted the arrangements on the Internet and we attended
the service. There were over 100 men and women at the
service - a testimonial to the man, Harvey Rait, my friend.
I have been mourning Harvey for a week, thinking about
this man I call my friend. I recalled the first time I met
Harvey at Bob Malloy's home in the fall of 1982. We were

going to join the LIST Group in Noiihport at Paul
Donally's home. Every second Sunday of the month, we
would meet at Bob Malloy's home and then motor on to
the LIST meeting. Approximately, five years later, we lost
the meeting room at the Huntington Library. We didn't
know what we would do for a meeting place and Harvey

came to our rescue - we could meet at his home.
Harvey had become our President. For ten years he would
wield the gavel with wisdom. Who will take over the
reigns I don't know.
Harvey was my friend! May you rest in peace! And for his
wife Sandy, and their children and grandchildren, we wish
you well. Harvey, we all love you . . .

[Bsttteary Backup for ±Jx& Z83

I went to my favorite electronics place a few days ago
and while there saw a bunch of AA battery boxes (battery
holders). These were odd ball ones with space for three
batteries but only had the contacts in place to use two bat-
teries. I had been thinking about doing the project by Tim
Swenson in the July 1995 UPDATE pages 43-44 in which
he made an external power supply for the Z88. BUT! with

these odd ball battery boxes at $0.18 each I could hardly
resist trying out the idea.

So I had the first part of the project parts and all I
needed was the plug to fit the external power socket and
the wire between the battery boxes and the plug. So into
the garage to find some old stuff and as I looked I remem-
bered having cut the cords with plugs attacted from the
odd ball power supplies I had accumulated. I finally found
them and I found one with a white cord which had a right
angle plug on the end. I tried the plug in the socket of the
Z88 and Joy of Joys it fit. Whether it made contact or not I
didn't know.

I determined the lead that connected to the center of
the plug and then soldered that to a red lead from the bat-
tery box. Then I soldered the black lead of that battery box
to the red lead of the other battery box and that boxe's
black lead to the other lead of the cord. Before I soldered I
slid heat shrink tubing on the wires and after soldering I
shrank it with heat from a match.

I put batteries in the boxes and tested for center posi-
tive andtor 6 volts. That checked, so I plugged it into the
problem Z88 and turned it on, so far good. Then I turned it
off and turned it over and removed the internal batteries
and back right side up I turned on the Z88 and it came on.
I turned it off and waited a good 20 minutes and again
turned it on and still working. I turned it off and installed
the internal batteries and checked, still came on when I
press the two shift keys. I unplugged the external batteries
and then I tested and the Z88 came on as it should.

Now I can safely change batteries without loosing the
contents of the Z88. I have a few project cases so I will
check into using one to hold the battery cases so it looks
neater. The cord that I put on the battery box is 6 foot
long. That gives more than enough slack to turn the Z88
over and remove and install new batteries. 0/0.

Bill, we met at the Milwaukee Fest back in 87. The
Chicago Area had a small SinclairFest April 26, 1997 at the
Holiday Inn in Elgin Illinois. We knew of the NESQLUG
fest but went ahead anyway. We had 7 people attend this
short notice fest. It was one table at a CoCoFest The
CoCoFest people asked me to find out if there would be
interest next year of combining a CoCoFest with a bigger
Sinclair FEST including the QL followers. As I see it,
Dayton is of less interest to Sinclair people and they might
rather attend an Elgin, IL fest instead. The Elgin event has
gone on for 6 years now and this was the first year Sinclair
was, invited. Wisconsin didn't come down but Watson,
Impellezzari and Walterman of Q-BOX came in from
Michigan, Nazir Pashtoon, Bobby Muth, Phil Kwitkowski
and myself came from the Chicago area. I understand the
Michigan men also went to Bedford a week later? I believe
we will do exactly what we did here next year and wonder
if it could be expanded to include the QL folks?

Also I saw the QL fest at Bedford called for
TS1000/ZX and Spec1rurn/TS2068 users. Could you guess
for me how many of those folks came to Bedford?

Hello Don,

Yes, I am willing to let the balance of my TS
inventory go for $1000.00 including shipping for the whole
works!

I really need the room and am no longer making
many sales of the product. I am lucky to sell $50 per
month any more.

I, too, would hate to see it all go into a dumpster, but
I have very little choice if no one buys it.

I have printed out some price lists from my inventory
program and am enclosing them. I think that most ail of
my TS inventory is included on these sheets. Anything
that is not listed would still be shipped out with the entire
package. Whoever buys one part of the lot buys all of it,
including the TS1000 items. It's an all-or-nothing deal.

If they are interested in the deal just tell them to send
the check and 1 will begin shipping the boxes out as soon
as I can get them packed up.

As you know, my vision has been getting worse of late,

Abed,

Since my QL is not really up to speed, I have not
worked on any new issues of the QHJ. The last one was
back in December. If you do not have it I can send it to
you.

I am starting to get the urge to do more with my QL,
but since my ED drives, modem, and mouse are in storage,
I really can't press forward. Even the disk drive I have
Mudged together is having problems. It can read HD but
can only format DD.

When is the next issue of ZQA due. I might be able
to put an article together about new freeware that I've

Do/ia/d Lambert

t least I got this started before the last minute
like the last two or so issues. I finally got
some stuff done on the Z88. Some can be
'interpreted as very Me from one standpoint.
From another it was a lot of time mulling over
why it didn't work or how should I do it. From the article I
submitted it will explain some of my problems BUT mostly
a failure for me to understand what I was doing.

Back to trying to do hardware.

picked up some connectors at Radio Shack
and will try for a Z88 to Z88 connector to
transfer programs from one to the other. If I
get that going I will report on that later. Also, I
have the parts to build a new interface for the
disk drive. All I need is the 25 pin to 9 pin converter. I will
have to peek into the hood to be sure there is nothing there
except wire. By hood I mean the cover that is put over a
connector (not one of those enforcers that lean on a lamp
post waiting for trouble). The original disk drive cable has
a hood that goes from 25 pin to 9 pin but I haven't seen
one locally or in the catalogs that I have.
Not that I don't distrust the Z88 but I take a peek at the
screen every few days (if I haven't been using one) to see if
the BAT LOW light is not on. Now that I have a back up
external battery I can safely change batteries without
loosing everything in the computer. For a while I sure was
having to reset the clock and date often. Hopefully I am
beyond that point.

Tim mentioned making a tie strip to control his cables

Off the Net

Every once in a while I'll spend some time checking
out what' s available on various QL related Web sites . Here
is what I found recently.

QLAY - QL Emulator for MS-DOS

Just released is QLAY, a new QL emulator for MS-
DOS. QLAY is a freeware program that emulates a 128K
or 768K. QL. It comes with the JS ROM, but ToolKit II
ROM images can be added. QLAY is at version .7, which
means that a lot of important features are not available.
QLAY does not recognize SER, FLP, HDK, or NET
devices. MDV image files are used for storing data.

QLAY requires a 386 with at least 16 Meg of
memory. A 486/66 will emulate a QL at full speed (some
what slower than QPC). Even though QLAY is a bit limited
in getting data in and out of it, it emulates a QL pretty well.
To demonstrate how it works, QLAY comes with an MDV
file with QUILL. When running QLAY with the QUILL
MDV file, after the emulator starts, it boots up into QUILL.
With my limited testing, QUILL works just like it does on a
real QL.

QLAY is written by Jan Venema of the Netherlands.
Jan plans to continue development to get a "real" working
QL on a PC. This will include support of QL disks, saving
files in the hard drive, printing to the parallel port, etc.
When version .9 comes out, Jan plans to make all of the
source code available.

QLAY is available from Jan's web page:
http://www. inter.nl. net/hcc/A. Jaw. Venema

Jonathan Hudson's Updates

Jonathan Hudson has a number of updates of his
software available on his web page. In brief they are:
£3 QTPIv. 1.62b (5/11/97) Beta test of QTPI. Includes
Q-Box console enhancement, Large (wide) screens, new
config options, etc.

S QDOS XPR v3.56 (5/11/97) These file transfer

protocols are needed for QTPI. The reported fix is it

correctly reports transfer percentage for large files.

£1 QFAX v2.82 (3/28/97) Minor update. Adds 200dpi

mode to piintfax and fixes "SAVE" bug in qfaxthing.

S ATP vl. 42c (3/19/97) Removes the random, irritating,

and invariably untrue "packet too old" message. This

update only contains the fixed binary file.

y UNPIC v0.02 (3/19/97) Tools to convert _scn and

_pic images to GIF, TIFF, BMP, or PCX.

y Winexplore v2 (2/13//97) C68 demo program to
explore window events, with source code and wm_prt
(read pinter with timeout) code. Modified for correct
timeout handling in action routine.

QPC Support Page

Marcel Kilgus, the creator of QPC, has put up a QPC
support page. It primarily lists the current versions of QPC,
SMSQ/E, Config, and the Installation program. Marcel
reports that he is working on version 1.20 of QPC. He is
also working on a different version of QPC that uses a new
emulation technique that should speed things up. Also on
the page is a PD version of QPC (version 1.15). There is
also a "hard disk" file that contains software, the manual,
and sample AUTOEXEC.BAT and CONFIG.SYS files.
This "hard disk" file is about 1.5 Megs, so it may take a
while to download.

Mmk QletStu^in^ With &lte 2068

Before we get into details about the many ways of
using the 2068 to gain textual information from the
Internet, let's briefly clear up some misconceptions and
errors from last time ! !

After listing an E-mail message to you, the mail
prompt "?", will appear. This initiates a reply, should you
type, "r" and press ENTER. This also deletes that
particular E-mail from your electronic mailbox. In order to
delete the letter only (without a reply) then simply enter
"d" after the mail prompt,"?".

Regarding Mailing Lists, a couple of months ago,
entering the line

lynx http://scwww.ucs.indiana.edu/rnlarchiv
would generate a long list of mailing lists for us to join.
Apparently, they have gone out of business. Currently, the
net is a model of freedom : freedom to use, lose, and
abuse.

When using lynx to navigate the web, there are two
contrasting ways of initiating a session:

Either lynx iisername@computername
or lynx, all by itself.

In the latter case, the Internet banner will fill the
screen. Now, you can ENTER

username@computername
in order to connect with username's site at computername.
In this case, we learn, that scwww.ucs.indiana,edu is not
found !

So, for cool sites on the Internet, use'em or lose'em
but do not abuse' em ! !

We wish to take this opportunity to announce the
opening of a new Message Base on SOL BBS, entitled
Advanced 2068 Topics, and dedicated to new applications
for our 2068 like ASAPfax, branch switching, and Internet
applications. SOL BBS is at 520 882-0388.

Now, we wish to pass along some inside information
on Surf n the Internet with the 2068 :

The idea is that we want to use the numeric keypad,
the top row on the 2068, to act as arrows for navigating
the web.

1 . Get the UNIX prompt $ onto the screen.

2. Enter the lynx command.

3. After lynx displays any "home" page, the cursor
stops for your response. So, press o, in order to display
the Options Menu.

4. Select the keypad option, by pressing k

5. Press the space bar, or BREAK key, repeatedly, till
the value of this option has the number keys pointing to
arrows, not to links

6. Accept this value, by pressing ENTER.

7. SAVE this setting and leave the Options Menu, by
pressing >.

OK, now that goes into your configuration file, which
is maintained by UNIX.

From this point on, we can use lynx to bounce
around the web pages, as follows :

ZXir QLive Alive! 13~

"1" acts as the end key (move to the end of current
web page.)

"2" acts as the down key (move down one link on the
current page.)

"3" acts as the page-down key (move down one
screenful.)

"4" acts as the left key (jump back to the previous
web page.)

"6" acts as the right key (follow the selected link to
the new web page.)

"7" acts as the home key (move to the top of current
web page.)

"8" acts as the up key (move up one link on current
web page.)

"9" acts as the page-up key (move up one screenful.)
This is not the only way to set up the keypad for surfing
the net, but we find it a profitable way to while away the
hours at the keyboard.

Navigation 101

We note, that key 6 above, "follows the selected link
to new page". On the 2068, a link is selected, by pressing 6
when tie link is listed at the bottom of the page.

What is a page? That's what you get, by ENTERing

lynx

or lynx username@computername on a line. It is a list of
information and information sources, called links. You
access the information source or "follow the link" by
"clicking on it". In the case of the 2068, you press 6 or
ENTER, while the desired link is at the bottom of the
screen. Try it, you'll Like it ! !

Should we get lost, Just press m, which takes us back to
the first web page.

We search for a pattern, by pressing 7 and going to
the top of the current web page, where we ENTER /pattern.

Using the number keys to navigate the web is actually
necessary, since special keys don't work on the 2068.
These include keys like end, down, page-down, left, right,
home, up, and page-up. Actually, Larry says to use SS-D,
in order to get the home key, but it never works for me!
So, here we go :

l.LOAD a web page, containing a large amount of data,
including color graphics.

2. Press p.

3. Choose from many Output Options.

Save to a local file =»> Saves the text of a web page to
a file on the UNIX host, where it can be downloaded, etc.
Mail the file ====»> Mails a copy of the web page to
someone.

Print to the screen =»> This is what I always use.

None of the color graphics appears, i.e., no garbage.
I just capture it to my capture buffer, if desired.

When using lynx to browse the web, we can get
hypertext (web sites), gopherspace (menus of menus), ftp
catalogs of files), telnet (access to other Internet sites),

Summer 1997

news (access to Usenet), ormailto (E-mail.)

Suppose we run into some good files, while using ftp
of or gopher. Then, we press d (download). Two choices
follow:

1. SAVE to disk.

2. DOWNLOAD to local terminal via ZMODEM.

#1 Will download the file to a disk on the UNIX computer.
#2 Will download the file right to the 2068, since I've never
had problems with ZMODEM.

In response to the UNIX prompt $. we can send ME
mail, by using the line: MAIL emanon@azstamet.com

But, if we are already in lynx, well we just use MAIL
TO: emanon@azstamet.com in order to accomplish the
same objective !

I mean, if we are using lynx to look at a web page,
listing a lot of links, then, we can use lynx with mailto to
SEND mail to any one at the other end of a link !

Next time, we will start, by clarifying any mistakes
from this time and finish up , by discussing the cool way to
access USENET !

KeepOnTIMEX'n

by Donald S. Lambert

CAUTION? This an attempt to document the
start of learning about the Z88 by a person that just might
be more senile than the person seen in the mirror in the
mornings appears to be. However, here goes.

I have two Z88s, one is the one that I sent in to have
the Z88 upgraded to V4.0 ROM with 512K RAM installed
internally. The other is a used (or reconditioned) Z88. The
upgraded Z88 came with a manual that was in standard
book binding and the pages were coming out; so the day
that the used Z88 came, I was in the process of removing
the pages and punching them to fit a half size binder I had.
I completed the task even after I saw that the used
computer came with a wire bound manual. I also have the
two books, one is the manual that came with the computer
and the other is the book "Z88 Magic" by Vic Gerhardi,
Bill Gerhardi and Andy Berry.

I have one questions; Is there any instructions for the
V4.0 ROM that are different than for the earlier ROMs?
That could explain why I have trouble with it.

I have had a Z88 for quite some but have not used it.
Part is the lack of ambition to get it going and part is that
the times that I tried to do something I ended up being
locked out by lack of knowledge of how to do it. Part is
that I do not find out how to do what I want to do from the
manuals that I have for the Z88. And part is that I didn't
really give it much thought about the way to store a
document in memory. Just recently a concept made it
more easy to reconcile the process of getting the document
into memory. I suddenly saw that if I considered the
memory as a mass storage device (and it is) then I could
more easily relate to that.

My progress has been anything but smooth. When I
heard that a disk drive could be connected to the Z88, I
JUST had to have one. So after finding and receiving a pair
through Radio Shack I ordered the hardware and software
to enable me to use the disk drive. But I soon learned that I
had to have more internal memory so I ordered a 128K
RAM and then I got the program transferred from EPROM
to RAM. Then I tried the disk drive to FORMAT a disk
and got an error message. So I tried again and still an error
message. So I finally used a different disk and this time it
worked. The first disk was bad apparently.

About that time I learned that I could upgrade to
Version 4 ROM and 512K internal RAM, so I did. Then

the gremlins hit. Seemed to work O.K. until after a while the
computer came back on and the keyboard was locked up.
I read and reread the manual and started out from scratch
and I again tried it and again, it woke up (screaming and
kicking) with a locked up keyboard. I tried it several times
and finally sent it back for repair.

It came back from Texas with a note bad keyboard
and now OK. but testing and it stayed asleep longer but still
woke up locked up. I reread all the material on initializing.
I had put the batteries in and I had reset twice and it had
not stayed in the sleep mode. I wondered why the
computer needed to be reset so I tried it with only one
reset and this time it woke up about 24 hours later. I tried
it again and had the same result-
So I again tried it and this time I did not press the
reset button at all with the straightened out paper clip. I
checked the computer several times, that is I Just looked to
see if the screen was lit. Finally after several days I pressed
both SHIFT keys and it came up and was apparently
normal. I even timed the auto shut off and that worked.
Now this computer has the version 4 ROM and 512K
RAM installed internally. I think it might have been a later
issue computer since in the upper left corner of the
computer it has Z88. The manual had the pages glued to
the spine and is listed as the fourth edition.

I ordered a second Z88 computer, used, this has a
version 3 ROM and nothing extra added to the computer.
The manual that came with it is a spiral bound manual and
the page count is almost the same. The upper left comer of
the computer has Cambridge Z88. At least it works like the
manual as far as reset and the sleep mode goes.

Today I tried to install the 128K EPROM that has
XOB (disk system software) on it into the updated
computer. I panicked thinking that the program had some
how disappeared from the EPROM but after I tried to
install it into the unexpanded Z88, 1 discovered that I was
supposed to be in the FILER to use the EPROM. There Is
No Cue Card Or Simple List Of Commands For This
Computer! This is sort of like when I first started with
disk drives on the TS-2068 and the LarKen LKDOS. I had
a file card with the commands on it. It took me a long time
to figure out on the LarKen system how to get an
AUTOSTART program to work with it was not on drive 0.
The program was on an 80 track drive and my 80 track

drive was drives 1 & 2. 1 work up in the middle of the night
with the answer. DO RAND USR 100: GO TO 1 (ENTER)
and then RAND USR 100: NEW (ENTER) and voila! up
came the program.

Back to the Z88s. I now have to see how to get the
program into the computer so that I can CHAIN it. What
is CHAIN? I don't know but it is a BASIC command. The
description of it in my 3rd edition The Basic Handbook by
David A. Lion runs to 5 pages so it is not an unknown
command. I will see if that makes it any clearer. It didn't
so that is no surprise.

Before I ramble on I will give some thoughts here
about the Z88. When I put the EPROM in that had the
XOB (disk operating system software) I had it stood on
edge to push the EPROM in and since I used an old wood
topped typing stand it was slippery. The EPROM seated
and the Z88 slipped in my hands and lit on the bottom and
slammed the cover shut and it beeped as it was supposed
to do. I guess I did not do it any damage but in the future I
will use a less slippery surface to support the Z88 when
changing any of the plug-in modules.

Also, I found it hard to pull out the modules till I used
a small screwdriver to slip in the end of the module and
thus lift it out. With my stiff fingers I cannot grip the
modules (or cartridges) so it is not possible to remove
without some sort of help.

Where do I store my two Z88s? I put them into a
hanging file folders. I have one of those $22 keyboard
covers (toppers) for one but the other I have none. I
suppose that the two SHIFT keys won't got pressed in the
hanging file but Just in case I made a deal out of cardboard
to lessen the danger of that. I cut a piece of corrugated
cardboard with the corrugations running the long way with
the dimensions of IP/a" by 18.375" . I made marks 8.5"
from either end and used a ruler to guide a screwdriver that
I used to pull along the ruler to sort of crush the
corrugations so that the cardboard would fold at that point.
The cardboard could be covered with wallpaper to make it
look neater. The splice is wider than the Z88, so that it

Civilization

ZX-TF.AM
The program is an adaptation from this
famous game by Microprose for PC's that
requires 6Mb of memory. But... the ZX-
81 has done it with only 1K of memory.

You are the leader of a small group
of people at the beginning of history and
you have to transform your people into a big
civilization. But you are not alone in the
world, there are others that will compete
with you. Unlike the PC version, the ZX-81
is your only competitor here.

At the start of the game, 4 numbers
are displayed - 2 for each group. Z and K
indicate the infrastructure, M and L the
military strength.

Before you know it, another set of
numbers appears - the ZX had attacked

helps hold the pressure off of the keys if the file drawer is
full.

I had a set of batteries show bat low, so I replaced
them and then checked the batteries with a Radio Shack
battery tester. The tester showed the batteries to be in the
yellow or replace area. A voltmeter will give a higher
reading since it does not load the battery. The RS tester
has a resistor across the battery to load it for the test.
When I put the batteries in I did not use fresh batteries.

I have XOB installed in both Z88s, but somehow it is
spelled differently in one. But CHAIN will fetch both into
the working area so it can be used. Next step will be to test
out the disk drive on both computers.

Here are the functions of the XOB (Disk Drive
Software)

CAT DELETE SAVE LOAD RENAME
FORMAT BANK=0 QUIT STATUS REPORT LINE

To use XOB you need to be in BASIC and CHAIN
"DISCMGR", when you press ENTER there will be the
XOB menu. Use the arrow keys to move around, when the
WgMghted bar is over the option that: you want to select
press ENTER and the prompt will guide you. It will initiate
with CAT highlighted. I had a disk that was not
FORMATted by XOB in the drive and pressed CAT and
the REPORT LINE reported 'Unexpected Reply'. Put the
highlighted bar over FORMAT and press ENTER and you
get on the main screen 'Are you sure?' press Y and
ENTER and it will FORMAT. The light on the drive will
blink fast a few times then will start to blink as it FORMTs
each track. Then it reaches the end and seems to go back
and check each track but at a faster rate. When FORMAT
is done the REPORT LINE will report 'DONE, 0K\ the
highlight bar is over CAT again. Press ENTER and you
will see on the main screen as a result of the CAT 'Free
Space 202240 Bytes'. There is no disk name.

The manual (9 pages of text) for XOB states that
there is a maximum of 40 files per bank with two banks of
files. Or 80 files per disk. But remember that the 3.5 disk

you and the numbers reflect your losses.
The civilian (infra-structure) losses are
always 3 times as much as the military
losses.

You have to make decisions on how
to divide your strength between the military
and the civilian keeping in mind your utmost
goal. Peace with prosperity or expansion
with war.

is only used on one side. Further experimenting will be
done as soon as I get into all the operations of the Z88
itself.

About the 3.5 disks that I am using. At a
computerfest I had a great buy of 3.5 disks. Even with a
problem that I just now discovered they are still a great
buy. The problem is that the little slider that controls the
write protect is missing. So I used some gummed labels to
cover the hole on both sides and since the labels don't like
to stick to the plastic I put Scotch tape over, beyond the
write labels (can't call these write protect since on the 3.5
disks you cover the hole to be able to write). When I
bought the disks I never thought to check for the write
tabs.

Back to the gremlins again. Both Z88s showed bat
low, so I had to replace batteries AND! both failed to retain
memory after the battery change. I panicked when neither
computer came up with a screen but did when I did the
hard reset. The one that doesn't like to sleep is back acting
up again. Thought I had that problems solved but no! Of
course I had to power down and remove all the modules
and get back into the FILER after replacing the batteries
and doing a hard reset. I can't remember just how long the
other batteries had been in the computers, so this time I put
a little sticker on the battery cover with that date typed on
it.

Now I am trying to get a file named and SAVEd to
the computer so mat I can get it to SAVE to disk. Maybe I
should PURGE the computer and start over with an empty
memory. This certainly works differently that the TS-2068.

I just learned that I was not giving the Z88 a hard
reset since I had failed to open the cartridge door. I will see
if that settles down the one with insomnia. I have started a
crib sheet to remind me as I go along.

I finally got a file SAVEd to the FILER and I got it
SAVEd to disk. But the commands are not like the book.
Or at least not like I read the book. But I did discover how
the disk drive stores the program on disk. By that I mean
the amount of disk space is used-up by a simple file. I had
two sentences, that was a file, and I SAVEd that to disk.
The smallest file on disk is 1280 bytes. So that means since
the limit of file names is 80 that it is possible that the last
part of the disk will not get used.

Progress is slow but I learn. I have learned that the
really important information is buried in the middle or back
of the manual. BUT! one important thing is to name your

external memory right after you install it or else if you
name it after you have SAVEd some files, you won't see
the file names when you go to the FILER. As I type I
wonder if it is in the CAT RAM if I designate RAM.O if I
will see the file names. I had a file SAVEd on disk that I
reloaded back to the Z88 and I finally accessed it by way of
:RAM,0//filename. I guess I could go back to the PANEL
and re-label RAM 1 to RAM 0. Or I could use INDEX to
see file names and then transport the files from RAM 0 to
RAM 1. Then erase the files in RAM 0. It would be easier
to remove the RAM cartridge and do a HARD RESET but
I think that if I try the transporting of files from one RAM
to another that I will learn more.

fn a sense FILER is a sort of DOS for some of the
other features of the Z88. If you think of the RAM as disk
drives then that is a good analogy. It seems that I spend a
lot of time resetting the clock and calendar. But it is easy
to go from PIPEDREAM to the FILER and use ESC to
exit FILER and go back to PIPEDREAM to exactly where
you were before.

Right now the Z88 with the 512K internal memory
finally seems to be working correctly. I am now timing the
time out feature and see if it will go to sleep as it is
supposed to. The last time it woke up with a frozen
keyboard, I did a soft reset and since then it seems to be
behaving. The time out ran to about 6 minutes before it
shut off and I put it to bed in the file folder in the filing
cabinet.

I do hope that I haven't bored you to tears with my
tale of woe but I imagine that many have went through a
lot of difficulties before they became proficient with their
computers. With one computer that does not operate
correctly and a poor map and an unknown road to travel I
have learned quite a bit I can see a lot of uses for the Z88
once I feel confident in its use.

If I was writing the manual or the book "Z88 Magic" I
would have put the order of ways to get going a lot
differently. I would have had the initialization with battery
installation first an then the inserting of the cards or
modules. Following that I would have the PANEL to set
American or European for the date and then the CLOCK.
Then the most important feature, the FILER would be
next. []FS is the command to use in the FILER to save a
file to RAM from PIPEDREAM. To LOAD use []FL.
They sure have that information buried. 0/0.

Daisy Be Good pan XI

by David Lassov

Well, guys and gals, we have attempted to brmg
Daisy into the 21st century, by making better use of RAM
and faster I/O operations.

In order to retain all Daisy's features in the process of
optimization, we have broken it out into four specialized
routines, which Loads and Executes rapidly.
We still use some virtual memory, but we incorporate
RAMDISK as much as possible, like for storing menus.
Then, instead of waiting for a file to LOAD from disk, we
only wait for a bank to switch, from Home to Dock and
back, again!

Of course, Zillion has some faster and larger
replacements for the Z80 chip, but they require a modified
Operating System. So, we limit ourselves to the Z80 chip,
LKDOS, and RAMDISK.

Our new and new and improved version of Daisy in
matched to our 9 pin printer, Ml 109 by Brother.
We wrote "stymn.B6", in order to bring out the best
features of our printer, and we wish to now consider how
the Busy signal is handled on the printer channel #3. The
2068 looks at the printer port 127 for a busy signal, IN 127 :

3 IF IN 127 = 229 THEN RETURN

4 GO TO PI

Note, that GO TO PI is a way of saving memory,
when all we need is GO TO 3, and we check that printer be
idle, before sending any control codes, OUT PO, so, say, to
the printer :

GO SUB PI: OUT PO, so (where we have po=127 and
zo=27.)

Also note, that my 9 pin printer has IN 127 = 102,
when it is BUSY, different from the 24 pin printer! But, the
way it is coded, we are looking for printer idle, all the way !

For our 9 pin printer, we use our Print Style Menu to
select among Pica, Elite, and Italic, after specifying
Condensed, Enlarged, and Double-Strike. Then, we "set"
the printer, by sending all the selected information out Port
127 by frequent use of GO SUB PI ... . After the BEEP, we
can ESCAPE to either the Format Menu or the Function
Menu.

Making use of the pre-selected parameters, the matrix
printer follows all our wishes, regarding print chain to print
out Daisy documents with.

By GO SUB il, we mean to PAUSE and read the
keyboard for input and PRINT our selection (where we
haveil=2550.)

2550 GO SUB sq: PAUSE oo: LET z=CODE
INKEY $ -CODE »o»: PRINT #RND;z: RETURN

With sq=2576, we call the Bill's SQuawk routine.

As discussed above, the Print Style menu, ps.Cl, is
loaded as a Screen String.

Summer 1997

^Byy^Bfcy Jones' suite ofWord Processors, that

^^HL g 0es by the name of Daisy ?

First, Daisy was conceived and implemented in the
days of expensive RAM and slow peripherals.

Second, Daisy is still marvelous, for getting so much
performance out of the little TS2068 computer.

Last, Daisy can be customized ("matched"), so as to
mobilize the best features of whatever 9 or 24-pin printer
be in use.

So, Daisy is a fine example of programming in
BASIC, using Virtual Memory. Today, "memory is
Cheap!"

Referring to the first article in this series, Winter of
1994, any necessary customization is limited to DOS
conversion, "stymn.B6", and "ps.Cl" .

Assuming that we have gotten over the DOS hurdle,
we are so familiar with printer matching, controlling, and
styling, as to be able to write our own "stymn.B6" and
"ps.Cl"

Bill wrote "stymn.B6", in order to bring out the best
features of his 24-pin printer, and we wish to consider how
the BUSY signal is handled on the printer channel #3. The
2068 looks at the printer port 127 for a busy signal, IN 127 :

8080 IF IN 127 = 253 THEN GOTO bu

8082 RETURN
where Bill has bu = 8080.

Now, when the printer is busy, Bill has IN 127 = 253,
and he checks for Printer Busy by GOSUB bu

Actually, Bill checks, that PRINTER is IDLE, before
sending any control codes, OUT po, zo, say, to the printer:

GO SUB bu: OUT po,zo

(where we have bu=8080, po=127, and zo=27.)

Mr. Earl Kielgass of Tempe, AZ uses the same CPI
cable for both 9-pin and 24-pin printers. He wonders why
it works for one but not for the other. Well, IN 127 returns
different values for 9-pin than 24-pin printers. His Word
Processor is Tasword, and, between 9-pin and 24-pin
printers, there may be many such differences in the CPI
interlaces.

For the 24-pin Printer, Bill uses his Print Style Menu
to select among Pica, Elite, Micron, and Compressed style,
after specifying Script, Expanded Height, Italics, and
Underline. Then, he "sets" the printer, by sending all the
selected information out PORT 127 by frequent use of GO
SUB bu ... . After the BEEP, he can ESCAPE to either the
Format Menu or the Function Menu.

Remember, at program LOAD, we pressed 3, 2, 1, y,
y. and y ? Well, in so doing, we committed ourselves to
assigned values for pr of 0, 1, or 2. pr=0 is for the 2040
printer. pr=2 indicates daisy wheel printer. But, pr=l gives
us the matrix printer, where all the variable selections come
alive.

By GO SUB iL Bill means to PAUSE and read the
keyboard for input (where we have il=2550

2550 PAUSE oo: LET t$=INKEY$: IF t$=
" " THEN GO TO il

With sq=2576, Bill calls the Squawk routine

2576 INK og: BEEP os/oj, VAL "40": RETURN

LOADed as a SCREENS string. It's contents should be

may fry the drive circuitry and/or the power supply.

Four boxes of floppy disks later, and after encounter-
ing several files that had been corrupted by my QL crash-
ing from time to time over the years, I had made WCOPYs
of all my programs and everything I had ever done that I
wanted to try using with QPC. using with QPC. Overall, I
am very pleased with the enhanced capability of QPC that
includes all the commands of SuperBASIC, Super Gold
Card, SBASIC, SMSQ/E, and Toolkit 2 which installs
automatically. It runs at an excellent speed with my
IBM/Cyrix 5X86 CPU.

I should note, however, that QPC manual to the
contrary, while my new QL drive happily did 1440-sector
formats/reads/writes on a couple DSHD disks I tried on it,
QPC would not recognize them as QL disks, but QL or
QPC-forrnatted DSDD disks work fine on both. QPC will
format DSHD disks to 2880 sectors on my HD PC drive,
which my QL Trump Card of course will not recognize but
a Gold Card system would.

Speaking of printing, in order to use a parallel printer
with the parallel IF driver provided with QPC, the
command in the DOS AUTOEXEC.BAT file that calls for
QPC to load should read: QPC-P:1 . This causes QPC to
look for parallel port LPT1, which is the default PC printer
port. QL programs such as the PSION suite require some
slight changes. With QPC loaded and running, and the
program disk in FLP1, enter LRUN INSTALL_BAS and
key the space-bar to select PARALLEL. Highlight the
driver file to be edited. Key F2/EDIT to change the
PRINTERJDAT file so the line for printer PORT shows
PAR as the one that is being selected. Key F5 to install
and save this edited driver back to the disk. This
PRINTERJDAT file may then be used with XCHANGE
by doing a WCOPY of it to RAM1_ and then, with the
XCHANGE disk inserted, enter the command line:

discovered any keystroke or combination that produces the
back-slash V

When writing a program that requires using \ to
produce a line-feed in a display or print-out, the ALTKEY
function can be used. First, HOT - GO must be entered to
activate ALTKEY. (HOT - GO also enables returning the
last keystroke sequence used by keying ALT ENTER
together as on the QL). Then entering ALTKEY "#",
CHR$(92) will produce \ whenever ALT and the PC \ key
are pressed. This and other ALTKEY definitions may be
SAVEd as a DO file if desired. With a disk in FLP 1, for
my keyboard definitions I entered the following as a direct
command: OPEN NEW #7, KEYS.PRINT #7 "HOT GO
":PRINT #7, "ALTKEY <#', CHR$(92)'':PRINT 47
"ALTKEY CHR$(39), CHR$(34)":PR1NT #7,"ALTKEY
'3','#":CLOSE. After ENTER creates the file KEYS on
the disk, VIEW KEYS will display the routine and DO
KEYS will activate it. Now ALT \ produces \, ALT
produces " and ALT 3 produces #. Note that CHR$(92) is
used to define the \ character, and using CHR$(39) and
CHR$(34) allows both ' and " to be properly nested in the
same PRINT "string''.

nominal capacity of over 248 Mb per disk. Those
accustomed to the space-conserving programming used
with Sinclair-based computers are likely to be amazed at
the sheer size of Windows 95 programs that can quickly fill
a hard drive. One that came pre-installed on my PC hard
drive takes up 1 50 Mb by itself

The hard drive format provided by QPC requires that
a WINchester partition be reserved for WIN files so, rather
than using my hard drive for WIN partition^), I am
installing them on ZIP disks also. My four hard drive
partitions are C, D, E, and F, so each 100 Mb disk in the
ZIP drive is seen by the PC as drive G, and by QPC as
WIN5_. The "formatting" of a WIN partition actually
creates a huge DOS file with a driver called QXL.WIN,
which can coexist on the same disk with other DOS files'
Allowing for the overhead required for this file and driver,
about 95 Mb is the maximum available for a WIN partition
on a 100 Mb ZIP disk. Be prepared to wait over an hour
for a partition this size to be done. If Stacker 4.0 is used to
create a compressed ZIP disk before doing a FORMAT
WINn, the WIN partition on it may be up to about 240 Mb
in size, or proportionately less if room is also being
reserved for DOS files.

When the QXL Gold card was advertised, I placed an
order that never materialized because the project was
dropped for the QXL 2, which I felt was too pricey for
what I wanted to spend to stay in the game. However,
when Jochen Merz, et al, came up with the QPC software
emulator for the QL, I ordered one from him. By the way,
the DM/dollar exchange rate of $1,725 premium per DM as
I write this, makes the cost quite reasonable, at less than
$140 including delivery.

When it arrived, after carefully reading the rather
sparse manual (38 pages on the included SMSQ/E operat-
ing system and 16 pages of QPC-specific info) I felt confi-
dent enough to install the program on the hard drive. Since
I had already made up a boot floppy disk for some pro-
grams that I was running on my PC under IBM DOS 7.0, 1
needed only to add another MENUITEM to the
CONFIG.SYS and AUTOEXEC.BAT files to boot DOS
from this disk and then load QPC from the hard drive. (MS
DOS supplied with Windows 95 has an almost identical
MENUITEM capability.) Once QPC is loaded, the DOS
boot floppy can be exchanged for a QL or QPC one, as the
DOS file is not called for again until an exit is made from
QPC by keying CTRL SHIFT SCROLL-LOCK.

As noted above, my next challenge was to try to get
my old QL Trump Card system running long enough to
transfer my 5 1/4" data disks to 3 1/2" ones that would
work with the single floppy drive now standard on all PCs.
I could not even get to the F1/F2 option-screen display.

Since I had noticed at times before that a sharp rap on
the QL case near the RESET button sometimes would get
it to boot up, I thought it might be that some fretting
(oxidation) had occurred on the contacts of this momen-
tary switch. I depressed the button and, using the thin ex-
tension tube on a spray can of TV tuner/contact cleaner, I
soaked everything with the cleaner. While it was still wet, I
snapped the button about 20 times. When I tried booting
up again - voila! Everything was working and, knock on
wood, has continued to work ever since. Unless it was an
absolute coincidence that the spray hit something else, like
a cracked trace, faulty solder connection or IC socket, what
a cheap fix for the frustration I had put up with for years!

Feeling I was on a roll, I attacked the next challenge
of replacing one of my two 5 1/4" quad drives with a 3 1/2"
TEAC FD235HF that I had bought a couple of years ago.
This is a jumper-configured type that is no longer made but
may still be found in some surplus outlets — all the new
floppy drives depend on the computer drive-controller to
sort out the configuration. I had bought a 5 1/4" to 3 1/2"
cable adapter kit (available from Frank Davis) about the
time I bought the drive, and after some trial-and-error ex-
perimentation with the jumper settings, I successfully
FORMATted my first 3 1/2" disk on the QL. NB: From all
documentation I have read, while wrong jumper settings or
even reversing the data cable adapter seems not to harm
anything, if anyone tries this at home make absolutely

What You Will Need

If you want to use this book successfully, you will
need the following:

An understanding of Spectrum BASIC. If you are total
beginner, you will almost certainly find this book too
complicated, and hence useless to you. If you can
understand most of the Spectrum manual, then you should
be all right. If you don't understand a word of the section
on using +3 DOS in machine code in the +3 manual, don't
worry, 'cause I don't either!

A disassembler or a monitor program. You can, in
theory, hack anything without one of these, but in practice,
it would be impossible for a beginner, and next to
impossible for someone experienced. My personal choice is
Hisoft's DEVPAC, but if you have the programs STK and
007 Disassembler (which were on the cover tapes of YS #75
and #77), that'll do fine for this book.

Some games to hack. Obviously business software is
out of the window because it's illegal to hack it, and you
don't need to anyway. Strategy and adventure games are
pretty unlikely to demand a POKE (although it's possible,
and I'll show you how I hacked an adventure later on), so
you're left with arcade and arcade adventure games. Most
of the time you'll want to find infinite lives and/or energy,
but there are always exceptions. This book concentrates on
games that you're likely to have, which are games which
have been on magazine cover tapes, or bestsellers.

Patience and determination. This is the most important
thing of all. Finding POKEs is challenging without any
— knowteripfi of how the program works, or even a knowledge
ZXir QLive Alive ! ~t7

of the language it's written in! So be prepared to do some
serious THINKING!

A Multiface or other "magic box" device. This is not
essential, but it is extremely useful, and a few sections in
this book require you to have one (but as few as possible, I
might point out!)

GLOSSARY

Breakpoint — An instruction put in by a disassembler
which will return control to it when it is executed. Also
something to do with tennis.

Crack/cracking — Writing a routine or executing some
code which will get round some element of a protection
system, enabling the user to put a POKE into the game.
Crash An undesired effect which the programmer or user
did not intend to happen. Classic example is the computer
resetting itself to give the old "(C) 1982 Sinclair etc., etc.",
or a whole load of flashing squares. Also a now defunct
computer magazine.

Decrypter — A short program contained in a protection
system which, when run will change garbage into
RUNnable code. You need to crack a decrypter to write a
hack for it.

Endless loop — The Multiface equivalent of a
breakpoint, put in hacking a protection system or doing a
stack trace. The computer will keep executing the same
code over and over again, indefinitely, unless the Multiface
button is pressed. See also endless loop (ho ho ho!)
Garbage — A block of machine code which does not
make sense to a human. The computer will attempt to
process it, but will almost certainly crash. Also what the
dustmen collect in America.

Hack — A self-standing program which when run will
load a game and activate certain cheats. Also the act of
getting round a protection system. (See also crack). Also a
lot of anonymous people from Scotland.
Headerless loader — A loader which does not contain
the first "header part" of a file specifying it's name, length
etc., but has it ready built into memory. This makes the
program harder to hack.

Interrupt — Small program which occurs every 1/50 of a
second, regardless of what the computer is doing.
Loader — Any program which reads a file off tape into
memory, and executes it. This may consist of simple
BASIC commands, a headerless loader, a turboloader or
even a protection system.

Operating system — The built in program into the
computer to deal with all the basic things like reading the
keyboard and loading software. This is BASIC in the case of
the Spectrum. Most protection systems deliberately confuse
the operating system or lock you out of it.
Patch — Replacing a bit of code with something designed
to hack it. This patch may consist of a jump elsewhere in
memory, or a breakpoint. Also something that pirates wear
on one eye.

POKE — The process in which a single byte of memory is
changed. Originally, games were hacked by one or two

Summer 1997

POKEs.

Protection system — A block of code which tags on the
front of a game's loader and prevents anyone from
accessing the code it is protecting. At least, that's what it's
supposed to do!

Trace — Looking through a block of code with the aim of
finding something specific (such as an infinite lives POKE).
This may be forwards, backwards, interrupt or stack trace.
Turboloader a loader which loads in a file off tape at a faster
speed than usual. This speeds up loading. The turboloader
may be hidden by a protection system.

PART ONE - The Basic Idea

Before we get down to some serious hacking, it will be
a good idea to know what we are looking for. Okay, I know
that some of you may think that this is pointless, but if you
don't know what you're aiming at, you'll never get
anywhere.

Basically, we are going to examine a program, and
change it so that certain instructions are altered so that the
game becomes more easier to the user. This may be in the
form of infinite lives, infinite energy, immunity, infinite
bullets etc.

The only way we can hope to do this is to understand
what is going on in the game. And because most games are
written in machine code, we're going to have to understand
that as well. Please don't be put off by the thought of
learning a new language; in fact you need know very little
machine code knowledge to hack most games.

To start with, we'll just look at infinite lives. Lives are
normally a small number, between 3 and 9 (although some
games may have more), and the common thing with all
games that have lives is that somewhere in the game, the
amount of lives are set as a definite number, and
somewhere else, the amount of lives goes down by one. In
order to get infinite lives, we would have to remove the
command in the program which decreased a player's lives.

You probably have and idea about how a lives system
would work in BASIC. Say if, for argument's sake, a
BASIC game had three lives, you would expect to see
something like...

100 LETLIVES=3
...contained in the program. Then, a bit further on, you'd
expect to see...

500LETLIVES=LIVES-1
In order to get infinite lives, we would simply remove line
500 altogether and RUN the program.

A similar idea appears in machine code, but the way
it's done is slightly different.

For starters, machine code doesn't have any variables!
You might therefore wonder how on earth the computer can
store anything. In actual fact, the computer can store
information anywhere in RAM, as you may well know, and
this is exactly what happens in machine code.

In Chapter 24 (The Memory) of the Spectrum manual,
there's a detailed description of the Spectrum's memory.
The best way to visualize the memory, I think, is to imagine
65,536 boxes, each one containing a piece of paper with a
number from 0 to 255 written on it.

Therefore, it is no problem for a computer to store the

number of lives in machine code, since it can just put it as a
byte in a memory location, leave it there, and come back to
it later.

You should be aware that in machine code, commands
are also stored in memory locations as bytes; so if you get
commands and data mixed up in memory, the computer
could easily try and execute the data, thinking it's a
command, and trying to execute it. Unlike BASIC, there are
no errors in machine code, and the computer can execute
anything it finds, so in this case you will get a crash. So
most programs keep program data and program commands
separately.

Anyway, in order to store three lives in machine code,
we'd put the number 3 in a memory location.
Unfortunately, we can't do this straight away in machine
code, and we can only do it by using what are called
registers.

Registers store information in the same way as
memory locations. They are bit more versatile though, as
you can perform calculations with them. All the same, they
are not the same as variables in BASIC, and are more like a
pair of hands used for counting.

The main register we'll look at for now is the A
register (sometimes called the accumulator), which can store
a single byte and have sums done to it.

What we would do to store the number three in a
memory location is to put the number 3 into the A register,
then put the contents of the A register (which are of course,
3) into a memory location.

The actual way of writing this in machine code is:

LDA,3

LD (#8000),A

Actually, strictly speaking, the above isn't machine
code at all! Machine code as the computer sees it is, as I
explained earlier, consists of many bytes in memory, which
are pretty meaningless to humans. So some people invented
assembly language (which is what the above is), where each
instruction carried out by the computer is given a name
(called a mnemonic).

The above program features one command used in
two different ways. The command is LD, which is
pronounced "load". This has notfiing at all to do with
loading a program from tape. It basically is a transfer of
information from one place to another. The comma in the
instructions is read as "with", so the whole instruction is
read as "Load A with 3". It now seems obvious that this
instruction is putting the number 3 into the A register.

The second command is also LD, but the way its used
is slightly different. The brackets mean "the contents of, so
the whole instruction is read as "load the contents of #8000
with A". (Think of a bracket as a byte in memory, where
everything in the bracket is part of that byte) Therefore, this
instruction would make the computer take whatever value is
in the A register, and store it in memory location #8000 (of
course, it could be any other memory location as long as it
is unused).

So the overall result of the two commands (normally
called operations) would be to put the number 3 in memory
location #8000.

Congratulations! You've just learned the first way to

hack. Clearly, if in a real program, we found these

tTa^ ™ S I We COm Change &e LD ^ 3 to something like
LDA,100 to get 100 lives!

Before we can do any "real" hacking, I'd better
discuss how "real" machine code is written.

Every machine code instruction contains and opcode
and some instructions need an operand. An opcode is'
simply the instruction the computer is going to do. Every
number from 0 to #FF correspond with a specific opcode
You can find a complete list of opcodes in Appendix A of
your Spectrum manual.

The operand is used whenever there is ambiguity over
something. If you look in Appendix A of the Spectrum
manual, you wffl see that the opcode #3E is "LD A^i" "n"
m this case can mean any single byte number i.e.: a number
from 0 to 255. But it's possible to put any number within
this range e.g.: LD A,3 or LD A,#40 or LD A,#80 etc. The
computer has to somehow know what data it is dealing
witii, and this is where the operand comes in. In machine
code whenever the computer comes across the opcode
#3E, it looks at the byte after the opcode, and assumes it's

a f,f Q± S °' tf COm P uter came ac **s the bytes
#3E and #40 in succession, it would put the value #40 in the
A register. In this example, #3E is the opcode, while #40 is
the operand^ After executing the instruction, the computer

lorn to ^ mming Code

*J?-** of <™ example, the opcode

is #32, i.e, "LD (NN),A". The ambiguity is in the address
where we are going to store the value of the A register In
this case, the operand takes up two bytes, hence the "NN"
which again comes after the opcode. You should note that
tins is an address in memory, and is always referred to as
two bytes. So you might expect the machine code
equivalent of LD (#8000),A to be #32 #80 #00. Except it
isn t! For some odd reason, in machine code, all two byte
operands are written the wrong way round, so the actual

machine code equivalent of LD (#8000),A is #32 #00 #80
mere is no hard and fast reason why, it's just vitally

important that you remember this.

In short, the program of the previous page is written as...
#3E#03#32#00#80

-.which takes up five bytes.

nppww^ 0 " 8 require Operands. For example,
DEC A (short for "decrease A", which subtracts one from
the A register) has no ambiguity at all. There is only one
way to decrease the value in the A register, so the
instruction only takes up one byte, in this case #3D No
operands are needed.

Right, time for your first bit of hacking? From what
we ve discussed above, we want to find, somewhere in the
game s code, a set of instructions which put the number of
lives into a byte in memory. So if the game had three lives
we could expect to see the bytes

#3E #03 #32

...unfortunately, we don't know where in memory the
number of lives is going to go, so we can't work out the
operands for the second instruction (#32). But in fact, we
don t need to, for if we find the above sequence of bytes in
a program, we can simp ly examine the two bytes after this
ZXir QLive Alive! ~~~

sequence to find out where in memory the number is being

So let's put this into practice and hack an actual game
For convenience I've chosen Sweevo's World, which
featured on a YS Cover tape Issue 60 December 1990 I
would have chosen a more recent game, but they all have
some form of protection on them. Besides, obtaining
infinite lives is relatively easy.

Getting the game in memory without it running is
easy. If you've typed out a fair few POKEs in your time
this will be no problem. Just MERGE the BASIC loader and
put a STOP statement before the RANDOMIZE USR

S ^^? en RUN ^ ogiam wait &r it to load,
unul the OK message appears.

Now we have the game in memory, we can load STK
and examine it. You have to be a bit careful here, because
STK occupies 6K of the Spectrum's memory. Although it
can be anywhere in memory, it possible to overwrite the all-
important lives code in the game with STK, so we have to
be careful. The best places to put STK are in the graphics
map or sound data. There's no easy way to tell where this'
is, so you 11 have to try pot luck. But it helps if you know
where the game loads to, so load up STK at any address
and press J and then Caps+9 to read in a header a couple of
times. Then read the headers of the three blocks of code
after the BASIC. They are:
Bytes: S 4000,1BOO
Bytes: M FB90,043D
Bytes: P 60E0,82B0
The first block is the loading screen. The second block is in
actual fact the game's music (but you wouldn't be expected
to know this), and the third block is the actual game itself
^erefore, we can put STK anywhere above
(60E0^82BO)=E390. For argument's sake, let's put it at
EA60, which is 60000 decimal. When we've finished
hacking, we can reload "Bytes: M" and run the program
Load up STK (after having stopped the BASIC and returned
with a STOP statement) at address 60000. 5244

Now at last, some hacking. Bearing in mind that you
start the game with five lives. Press Q to search for a byte
Enter the address we want to start searching at as 60E0

Mowing^' 8 Stait ° f ^ N ° W ^ "
#3E #05 #32

These are the search bytes we described on the previous
page Keep pressing N for "next" until all of the memory
^ r bee " **** Y ou will get the following addresses-
vox. and EEDC. You can ignore the one at EEDC, because
it « m the middle of STK and outside the main game code

Z^n l t m Z 3USt &e one at 905C - E ^ edit and type
#905C. You'll see the following bytes-

3E0532 1A 61

So this teUs us that the computer puts the number five in
box number 611 A (remember that 2 byte numbers are
reversed!) Now to hack the game, we simply change the
number 5 at 905D to any number of lives we want (the
maximum is #FF).

t> A .J?° W ' g6t ° Ut 0f STK - reIoad Ae " B ^s: M" file and
RANDOMIZE USR 24800 (the original command in the

23

Summer 1997

BASIC), and hey presto - you will have whatever amount of
lives you wanted!

All that remains to do is to write a proper hack for it.
905D is 36957 in decimal, so your hack would be something
like "MERGE the BASIC loader, and insert POKE 36957,n
before the RANDOMIZE USR statement, where 'n' is the
number of lives."

And it's as simple as that. If you can understand what
we've done so far, you're doing well, so stick at it.

Any unprotected game like Sweevo's World is hacked
in the same way, except you will probably have to reload
STK to a different address, and you may find that in your
search for #3e #32, you may come across several locations
in memory outside STK that have this pattern. In this case,
you'll have to use trial and error to work out which one
holds the number of lives.

It is, of course, perfectly possible for you now to find
'number of lives' POKEs for any unprotected game under
the sun, and in the early days of Spectrums ('82-' 84), this
would have been perfectly adequate. Of course, what your
really need is the real nitty gritty - INFINITE lives. This is
done by taking things just a step further.

What you basically need to do is find out which
memory location the number of lives are being put in. Then
you need to search for parts of the program which put the
value of that memory location in a register, subtract one
from it, and put the new value in the register back. Then you
have to rewrite the code slightly so that the computer
"forgets" to decrease the value in the register, and simply
puts the old value back in again.

Coming back to Sweevo's World, we already know
that the number of lives are stored at memory location
61 1A. I normally refer to this memory location as the "lives
store" for obvious reasons. All we have to do is search for
all the occurrences of the address of the lives store. So,
search for #1A,#61, and you will find it referred to at the
following addresses:

779B 8160 81A9 905F EEDC
You can ignore the one at EEDC because it's in STK, but
you can also ignore the one at 905F, since that's part of the
lives setting routine we discussed earlier. So the routine to
decrease the number of lives must lie at one of the other
locations.

You should note, that any instniction that involves the
lives store will begin at the byte before, because 1 A and 61
are two byte operands (see page 3 for more about
operands).

So for starters, press E to edit an address and type in
#779A. You'll see the following:
779A-3A1A61 C3 61 99

If you look up 3A in Appendix A of your Spectrum
manual, you'll see it corresponds to the instruction LD
A,(NN). This is simply a reverse of the LD (NN),A
instruction, in that the value of a memory location is put
into the A register. This is important, because subtraction of
any sort can only be done in a register, and usually in the A
register.

After the computer has executed the three byte
instruction 3A 1A 61 (which is LD A,(61 1 A in mnemonics),
it re pontes fhft instruc tion CI Tf you look Up C3 in

Appendix A of your Spectrum manual, you'll see it
corresponds to the instruction JP. JP is short for "jump",
and is in a sense like GOTO in BASIC. What the computer
does is to jump to a location in memory. As you can see,
there is ambiguity as to where it is going to jump, so we
need a two byte operand. Like the ones me have met before,
the bytes are written the wrong way round. So C3 61 99
means JP 9961. In this case, the computer would go to
address 9961, and start executing code from there.

It is possible that the code to decrease the number of
lives is at 9961, but is unlikely, because it pointless to have
to jump to a completely different area of memory. So we'll
leave this part of memory, and go onto the next instruction,
at 8160. Press EDIT to leave the editing procedure, and edit
address 81 5F. You'll see the following:

815F-21 1A6135
21 is the instruction LD HL,NN. HL is another register like
A, but its main difference is that it can store two bytes at
once. So LD HL,NN requires a two byte operand, whereas
LD A,N only requires one. So here the instruction 21 1A 61
means LD HL,611A. The next instruction, 35 doesn't need
any operands, and is the instruction we've been looking for.
35 means DEC (HL). You've already come across brackets
meaning "the contents of, so as you might have guessed,
DEC (HL) decreases whatever is at the memory location
with the same number as HL by one. In this case, we know
that HL is 61 1A, because we've just set it in the last
instruction. So DEC (HL) will decrease the value of
whatever is in memory location 61 1 A by one in this case.

But we already know that the number of lives is stored
at memory location 61 1 A. So clearly DEC (HL) is going to
decrease the number of lives by one!

What we need to do to make an infinite lives POKE is
to somehow overwrite the DEC (HL) so that the computer
doesn't decrease the number of lives. There are two things
that can be done. Firstly the address containing DEC (HL)
can be replaced by 0. The number 0 relates to an instruction
called NOP. NOP is short for "No operand", and in short
means absolutely nothing! When the computer encounters
the instruction NOP, it will do nothing and execute the next
instruction. So if we overwrite DEC (HL) with NOP, the
computer won't decrease the number of lives, but do
nothing instead. The vast majority of POKEs have the
format POKE address, 0 for the reasons described above.

If you run Sweevo's World changing the DEC (HL) to
NOP, you'll find you only get one life instead of five! In
this case, you should overwrite the DEC (HL) with OR
(HL). OR (HL) is a single byte instruction, B6. Don't worry
about what it does, because it isn't important. What is
important is to remember to do this if you only get one life.

Rerun Sweevo's World, replacing the DEC (HL) with
OR (HL), and you'll have your infinite lives! The DEC (HL)
is at address 8162, which is 33122 decimal, while B6 is 182
decimal, so the POKE would go something like "MERGE
the loader, and put POKE 33122,182 before the
RANDOMIZE USR statement, RUN the program and
restart the tape."

Now we've covered the rudiments of machine code
involved in hacking, we can look at more detailed ways of
finding POKEs.
